The Influence of Metallicity on Star Formation in Protogalaxies
A. -K. Jappsen, S. C. O. Glover, R. S. Klessen +1
In cold dark matter cosmological models, the first stars to form are believed to do so within small protogalaxies. We wish to understand how the evolution of these early protogalax…
A Mid-Infrared Spitzer Study of the Herbig Be Star R Mon and the Associated HH 39 Herbig-Haro Object
M. Audard, S. Skinner, M. Guedel +3
We report on initial results of our Spitzer Cycle 2 program to observe the young massive star R Mon and its associated HH 39 Herbig-Haro object in the mid-infrared. Our program use…
Star formation at very low metallicity. II: On the insignificance of metal-line cooling during the early stages of gravitational collapse
A. -K. Jappsen, S. C. O. Glover, R. S. Klessen +1
We study the influence of low levels of metal enrichment on the cooling and collapse of ionized gas in small protogalactic halos using three-dimensional, smoothed particle hydrodyn…
Stellar Mass Spectra from Non-Isothermal Gravoturbulent Fragmentation
R. S. Klessen, A. -K. Jappsen, R. B. Larson +2
(abridged version) Identifying the processes that determine the initial mass function of stars (IMF) is a fundamental problem in star formation theory. One of the major uncertainti…
The Chandra Fornax Survey - I: The Cluster Environment
C. A. Scharf, D. R. Zurek, M. Bureau
We present the first results of a deep Chandra survey of the inner 1 degree of the Fornax cluster of galaxies. Ten 50 ksec pointings were obtained in a mosaic centered on the giant…
Far-Ultraviolet Surveys of Globular Clusters: Searching for the Products of Stellar Collisions and Near Misses
C. Knigge, D. R. Zurek, M. M. Shara +3
Far-ultraviolet (FUV) observations with the Hubble Space Telescope are an excellent way to find and study the hot, blue stellar populations in the cores of globular clusters. These…
